When I built libgeotiff on my SAR team's Ubuntu machine (one that had been upgraded from 5.10 through 6.06 to 6.10) I did not see this problem, but today I did a fresh install of 6.10 on a new laptop and there it was. I have no idea why there should have been a difference, but there was, exactly as you and John have both seen. I tracked down the issue, with the help of google on the error message. The really helpful search result was this one: http://comments.gmane.org/gmane.linux.redhat.fedora.general/217819 The issue is that libgeotiff's configure script looks around for how to build shared libraries, and concludes that it needs to do "ld -shared" to make libgeotiff.so from its object files. This is, however, completely incorrect with GCC 4.x. The right thing to do is "gcc -shared" The workaround is to configure libgeotiff by overriding its internal probe for the way to do shared libraries. That is, libgeotiff should be built with ./configure --with-ld-shared="gcc -shared" make sudo make install Unfortunately, if I were to slam that into get-maptools, it would probably break the script for some other platform. Instead, I'm documenting the cheesy hack I did on my temporary copy of get-maptools.sh, and adding that to the wiki. I've tried to make it so that anyone googling on the error message would get a quick answer to their question, too, so it has unfortunately bloated the step-by-step instructions somewhat. It's still pretty straightforward. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM "And, isn't sanity really just a one-trick pony anyway?
